MACKIE THUMP18SV4 18" Powered Subwoofer

Description

The Mackie Thump18Sv4 active subwoofer is designed to add powerful low-end performance to any PA system, delivering deep bass and punchy impact for live events, DJs, venues, and mobile sound applications. Combining a high-efficiency 1400W Class-D amplifier with an 18" high-performance woofer, it produces up to 132 dB SPL with impressive low-frequency extension down to 28 Hz for floor-shaking bass response.

Built for professional use, the Thump18Sv4 features a rugged yet lightweight enclosure with integrated handles for easier transport and setup. Selectable high-pass modes allow seamless integration with Mackie Thump loudspeakers or other PA systems, while variable crossover control provides additional flexibility for customised system tuning.

Designed for versatile deployment, the subwoofer includes stereo XLR inputs and outputs, mono or stereo summing options, phase inversion, and adjustable output levels. Pole mounting compatibility allows a full-range loudspeaker to be mounted directly above the subwoofer for a compact, professional PA setup.
